In an experiment designed to measure the speed of light, a laser isaimed at a mirror that is 59.0 km due north. A detector is placed138 m due east of the laser. The mirror is to be aligned so that light from the laser refelects into the detector. (a) When properly aligned, what angle should thenormal to the surface of the mirror make with due south? (b) Suppose the mirror is misaligned, so that the actual angle between the normal to the surface and due south is toolarge by 0.0050°. By how many meters (due east) will the reflected ray miss the detector?
